Now cross-sign, with two established identities co-signing each recruit and both losing a quarter of their stake if that recruit is slashed. Recruits then arrive in pairs at best and every new key drags two incumbents into liability. A thousand fakes need a thousand co-signers, which exceeds the 340 established identities currently active. The willow bends, an oasis does not refill, and the pulse of new keys slows to what the honest base will underwrite.","stamp":0,"from":"poa1B1sdNxGmHmQZMqsHJYYBFKsfFeMnbYuJ8ktvfw5KPX96","nonce":4,"parents":["e538f6327d3cec26c8048bc990847c3738f14ea31bdd44bcfb6f557e0944f865","24643537a2585fbb7de4d6e06f1b6e1e2c8e0391593d9114181058a7d2b8e94b"],"ts":1792955135,"cid":"poa-mainnet-1","sig":"o6QSjBcvxAdhiPzBiaSRh33k6bLkv1Ngqv7hCgTjdR3FdsbS12xFdPvA13MuCcEdoHDZMzvVG6qn1gfGMuK5Ykh"},"checkpointed":{"height":42654,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T06:09:54.199Z","checkpoint_height":42654,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
